3.2v

3.2v
4 dimms and you must disable command per clock (aka you should have 2T enabled). this is not a RAM nor CPU issue, its a design limitation of the amd64 platformQuote:

even SPD to it can break down on 4x512MB gold memory
i run only my system in 2T ang cry
4 DIMMS is 2T no matter what speed in A64 ...Quote:

Its normal if u dont cool the zone enough.
Twinmos 2700 256mb dual sided bought early 2003. Rated for 2.5,3,3,7
Chips read:
M.tec
02474
TTD7608F8E60B
Will do:
230mhz 2.2.2.5 2.9v
Probably will do more since my old NF7-S would only go that far.
Yeah, I have 4 sticks of 1A4T SP3500 and found that issue with one.Quote:

Did some testing to try to find the best matched pair before burn-in, 2-2-2 @ 2.8v, 3.0v, 3.2v for max memtest stable (when I say stable, 10-20 passes, just wanted an indication of what they would do).
All of the sticks were about the same up to 3.2v, 2.8v = ~220, 3.0v = ~230.
At 3.2v, 3 sticks would do ~240, but the other wouldn't do anything but error, and error hard, even at the speed it was error free at 3.0v.
Out of the four sticks, the best performer was one that had been given some burn-in previously since it was from an earlier batch than the other three.
The other two sticks which did not error above 3.0v have been the ones I've been playing with this week, gave them a bit of burn-in and they're responding well (2x512Mb 2-2-2-5 252mhz@3.3/3.4v), doing 255 @ 3.4v but need more tweaking time to get stable. (I'm new to BH so it's a learning curve for me, may have been a setting thing, they seem to have a volt/setting range that you can't deviate from much).
I'm planning on giving the uncooperative stick a right royal voltage bashing to see if it will shake it's reluctance to work with volts, should be in the next couple of days, I'll let you know how it gets on.
My hunch is that it's 50/50 burn-in/settings for me. I have found a lot out about these sticks from working with just the 2 over these past three days, they are very finicky about having the right volts for the right speed with the right settings. TCCD seemed more forgiving since I never had to worry about having the right voltage for the speed, it was always 2.7v.
Big ups to Rabbi for supplying some awesome sticks, this holiday is proving to be great fun. :)
Does TMSP nowadays come with Brainpower PCB instead of KO-6633?
Still KO-6633..
guys, this any decent for my "xtreme Twinmos memory"? :p:
It's not UTT but hey....
Brainpower PCB
Mtec labeld Chips
50B's & AMT in the serial
They do:
238MHZ 7-3-3-2T at the moment and I've got them to 6-3-3-2T but I lack the PSU for it at the moment :)
is this any decent for these chips?
^ Depend on voltage? :confused:

it's @ 2.9Volts
Doesn't look good if I have to RMA any of my sticks. Luckily I bought 4 sticks of TMSP with Winbond BH5 chips (two in family computer running at stock :D) so if any goes wrong and I RMA only to receive non-Winbond, I've got 2 spare :D.Quote:

They're also older than when the UTTs seem to have started appearing. I got those two modules around September of last year.
alot of different companies used the winbond chips. just post a pic and someone here can verify for you.
Another good way of checking is setting the Vdimm to 2.8-2.9v and setting the timings @ 2-2-2-5 1T 200mhz. If it boots and runs memtest, it's UTT (most likely).Quote:

hi guys..
i Bought 2x512 twinmos pc3500, this week. but there are not bh5.
de last 4 code is: 1AAT.
14AT is utt bh5 but this???
LOOK the image
http://www.infohard.mpsnet.cl/twinmos.jpg
chip code:
A2S56030BTP
515ACN1P
Taiwan - 5
any info to tihs ram?
sorry my english
:D
The Twinmos web site is still saying their SP 3500 512mb sticks still have "BH-5 dies" but they also say "*All products specification change without notice". I've never seen that extra sticker in the middle of the stick - is that gold leaf on the sticker and IC? That sticker also has a recent production date so it might a revised version. Only way to tell what you have is to test it. Post your results ASAP. :)
those are powerchip ic's most likely, just like cadt & aadt.
i've seen aa-t's couple of weeks ago and ic's were labeled psc.
Got 2 512MB SP-3500 with 44B (BH-5) chips, and fitted them with individual chip-sinks (pic is coming). I`m not so familiar with BH-5 settings (got G.Skill GBLA), so if anyone could point me in the right direction, it would help me alot! Aiming for 250 at 2-2-2-5 1t... Yeah, I know, I might have to dish out for VX or Redline to obtain that....
I have 4x 512Mb SP-3500 BH-UTT that will all do 250mhz at these settings:Quote:

same settings but 3.4v @ 245mhz for all four sticks.
2-2-2-7-12-2-2-1-1 should work like a charm with the same voltage :toast:Quote:
